You missed quoting the part where I describe the on clauses you need to distinguish between "them" and "me"

Me: u.uid in (player...) and (s.uid = u.uid)
Them: u.uid in (player...) and (s.uid <> u.uid)

        SELECT

                c.msg

        FROM    words_chat c 

        JOIN    words_games g USING (gid)

        AND     s.sid    = in_sid

        AND     (c.uid = myself.uid OR NOT opponent.muted)

        

        ORDER BY c.CREATED ASC;

And get the syntax error which don't quite understand:

ERROR:  missing FROM-clause entry for table "s"

LINE 57: ...yself.uid IN (g.player1, g.player2) AND myself.uid = s.uid) 

                                                                 ^

Probably because "myself" needs "s" and vice versa?

Well, that is basically why I was going on about the oddity of having social be a part of the main query.  Personally I would write it as "myself.uid = in_uid", but you don't have an in_uid to reference.  Decide how you want to do something equivalent.
